About the game
You are the captain of a small ship, and your fleet has stopped listening to you. The plan is simple: sail out, find the other captains one at a time, and take all thirteen of them down to claim the top spot. The game is played from the side, with your ship on the left, the next rival on the right and a friendly little sailor with a cannon on each deck.
The twist is that your cargo is made of dice. At the start you roll for it, and the pips showing on the dice you carry add up to your ship's hit points. Those same dice decide how many dice you roll when it is time to shoot, so a bigger load is both sturdier and more dangerous. The catch is the number the game is named after: a ship whose cargo total lands on the unlucky number is in trouble, and even rolling it in a fight has unpleasant consequences, so a big haul is not always a good one.
Between fights the sea is not empty. You may meet merchants who sell you something, carpenters who patch the ship up and sailors who want to join the crew and lend a hand. Each ship you beat leaves you a little stronger, and each new rival is a little tougher than the last.
Antti Haavikko made Coup Ahoo for js13kGames 2024, where the whole game, zipped, had to fit in 13 kilobytes. The theme that year was Triskaidekaphobia, the fear of the number 13, which explains the thirteen opponents.
Playing it here
Click Play, then click the game once to start. The first screen asks you to roll for your cargo. After that the buttons in the lower right corner drive the game: set sail, shoot and pick what you want when a choice appears. The game is drawn in widescreen, so on a tall window you will see bars above and below it. Pressing M turns the music and sounds off and on. Nothing is saved: a new visit starts a fresh voyage.

A few things worth knowing
More dice is not always better. Your cargo total is your health, but a high total also puts you close to the unlucky number. Think about what each trade or pickup does to the sum.
Look before you buy. Merchants and carpenters change the dice you carry. Fixing a weak spot is usually worth more than a showy upgrade.
Fights are short. A volley is a handful of dice, so a single round can swing a battle. Do not be afraid to restart if a voyage goes badly.
